I just sold my iPad 1 on Craigslist and the guy wants to see it in action before purchasing. Sounded like an honest guy and not the most familiar tech products. Anyway, I have no problem showing it to him in action. I will wipe it before we make the transaction however. I remember the iPhone 3G used to take quite a while to wipe but the iPhone 4 was fast. How long will it take for me to wipe the 16gb iPad 1 after I make the transaction with this guy?
